According to Bitcoin News, Dario Amodei, co-founder and CEO of Anthropic, stated to lawmakers in the U.S. Congress that the development of open-source AI is entering a "very dangerous path." Once powerful AI models are released in open-source form, developers will lose effective oversight over the usage of the models, including the inability to monitor abuse, revoke access, or dynamically update security mechanisms, thereby increasing potential risks.Dario Amodei mentioned that compared to closed model systems, fully open models are more difficult to implement continuous control over security governance, which may lead to irreversible abuse risks.

According to CoinDesk, Binance founder Zhao Changpeng stated that the significant decline in the crypto market in the first half of 2026 does not have a single cause. Geopolitical tensions, investors shifting funds to AI, and the typical four-year cycle of crypto may collectively lead to the continued decline of Bitcoin and other crypto assets. Bitcoin reached a historical high of over $126,000 last October and has since fallen by about 50%. At the beginning of this year, Bitcoin opened near $89,000, briefly rose to just above $96,000, and then dropped to around $60,000.In the long term, the crypto industry will continue to develop, and the demand for fintech will increase as the number of transactions continues to rise, so they are not concerned about the industry itself or short-term price fluctuations. They stated that emerging industries like AI are absorbing "hot money" from the crypto sector, but in the long run, this could be a positive factor. When discussing prediction markets, Zhao Changpeng mentioned that the rapid growth of prediction markets as tools for price discovery and liquidity is a good thing for the public.Regarding regulation, Zhao Changpeng stated that separate bills like the U.S. Clarity Act are important but more tactical matters that will not determine the long-term growth of the crypto industry. He hopes the Clarity Act can pass and believes that if U.S. legislation is delayed, other countries may take the lead in advancing rule-making.Zhao Changpeng also mentioned that if the U.S. Democratic Party regains control of at least one chamber of Congress after the midterm elections, there may be a review of Trump's support for the crypto industry and his pardons for crypto executives. Zhao Changpeng stated he "has nothing to hide" and is willing to cooperate if relevant parties seek information. When discussing political influence, Zhao Changpeng said he tries to stay away from U.S. politics but believes that any anti-crypto individuals may now lose a significant number of votes.

According to Bloomberg, the European Parliament's Economic and Monetary Affairs Committee (ECON) has approved a position paper on the legal framework for the digital euro, paving the way for negotiations with member state governments and the European Commission on the final rules. The plan will advance both the online and offline versions of the digital euro, with the European Central Bank aiming to complete the launch by 2029 and to conduct a pilot within the next 12 months to validate the infrastructure in real-world scenarios. Regulators hope that the digital euro issued by the European Central Bank will reduce reliance on Visa, Mastercard, and dollar-denominated stablecoins, while providing a "secure European domestic option" for retail payments without eliminating physical cash.

About 1,200 small and medium-sized enterprises have joined the Japan National Business Enterprise Pension Fund (located in Okayama City), which plans to start investing in cryptocurrencies in the fiscal year 2026. There have been some cases of Japanese companies investing in crypto assets, but it is still relatively rare for domestic pension funds to participate directly in crypto investments.The fund plans to allocate about 1% of its total assets to cryptocurrencies and will do so indirectly by investing in passive funds managed by large hedge funds that include various crypto assets. In terms of asset allocation, its structure for the fiscal year 2025 is: 80% yen, 15% US dollars, and 5% other currencies. In the fiscal year 2026, it plans to adjust to: a reduction of yen to 70%, an addition of 10% allocation to developed country currencies, and the remaining 5% allocated to emerging market currencies, gold, and crypto assets.The main purpose of this adjustment is to diversify exchange rate risk. The fund's executive director, Ai Kuchi, stated that the status of the US dollar as a global benchmark currency may be weakening, which is why they decided to reduce their holdings in US dollars. At the same time, he pointed out that the correlation between Bitcoin and the US dollar index is almost zero, making it a tool for hedging against currency depreciation risk and enhancing the portfolio's ability to withstand inflation.

Tether CEO Paolo Ardoino announced that the Bitcoin mining development kit has been upgraded to version 0.2.0, achieving its first complete end-to-end open-source operation. The latest version supports the full open-source deployment and operation of the entire Bitcoin mining machine development stack, and can display the mining machine's hash rate output data in real-time. Developers can directly launch the system and observe the real-time generation of the actual mining machine's hash rate on the interface. Its goal is to build a foundational technology framework that connects intelligent systems with physical infrastructure.

Binance founder Zhao Changpeng (CZ) participated in an exclusive interview on the Galaxy Brains podcast with Galaxy Research Director Alex Thorn. CZ stated that he is no longer operating the trading platform, allowing him more time to communicate with developers, and he is excited about some new features of BNB Chain. He mentioned that BNB Chain is developing the next version, which will be faster, cheaper, and include more privacy controls.CZ also advised blockchain developers not to make major upgrades during a bull market, but to push forward significant updates during the quieter times of a bear market. CZ said that he was skeptical about RWA (Real World Assets) about a year to a year and a half ago, uncertain whether the related assets would be traded or could develop. However, the speed of RWA's development surprised him, as stablecoins, oil futures, AI stocks, and others have gained good acceptance in the crypto community. This indicates that many people globally have been looking for access to these assets.Crypto should not be seen as an independent industry, but rather as a new technological tool that makes financial transactions faster, cheaper, and more transparent. He believes that traditional financial institutions can use blockchain, and crypto companies can also provide services similar to traditional finance, such as loans, savings, stock trading, remittances, and payments. In the future, there should not be a clear distinction between traditional finance and crypto, but rather a more globalized, faster, and lower-cost financial industry.

According to Rest of World, in order to significantly reduce operating costs, American developers and startups are accelerating the adoption of Chinese AI models such as DeepSeek, Minimax, and Kimi. Due to their high cost-effectiveness in handling common tasks like code writing, the market share of Chinese AI models is rapidly increasing. Data shows that in May, the Token usage share of DeepSeek on the service provider Vercel platform surged from less than 1% to 17%. Additionally, it is reported that Microsoft is also exploring the use of DeepSeek or other open-source models as a low-cost alternative for Copilot.However, despite the popularity of Chinese AI models in the market due to their price advantage, many American companies and developers choose to access these models indirectly through local servers or American cloud service providers, constrained by domestic political scrutiny and data security concerns. This has led to Chinese AI companies facing high usage rates while still struggling to effectively convert traffic into substantial direct revenue and long-term enterprise-level customer trust in the U.S. market.

According to Jinshi reports, Federal Reserve Chairman Waller stated that persistently high prices are a burden.

Syscoin released a bridge security incident report, disclosing details of the UTXO-to-NEVM bridge vulnerability incident, which reportedly led to approximately 5 billion SYS being unauthorizedly released on the UTXO side. The related funds have since been returned to the official recovery address and destroyed through the standard OP_RETURN method, making them unusable by the protocol again. The on-chain reported SYS supply has been restored to the expected value, and the bridge function remains suspended while the team completes the final review and fixes.Syscoin pointed out that it will fix the cross-layer parsing defects. The core lesson from this incident is that cross-layer systems must uniformly standardize data processing, and any ambiguous bridge proof should be considered a default failure.

According to official social media news, the third session of the Huobi Master Lecture "AI Agent Economy and New Opportunities in Crypto" will officially start today at 19:00. Han Feng, an independent researcher at Harvard University, a corresponding member of the American Association for Artificial Intelligence (NAAI), and a lifetime member of the Bitcoin Foundation, will be invited to attend and share insights on the theme "From H2A to A2A," discussing the new trends in the integration of AI and Crypto against the backdrop of the rise of the Agent economy, interpreting the collaborative network of intelligent agents, on-chain economic systems, and potential development opportunities in the future digital society.

According to BBX data, yesterday's interest rate hike in Japan coincided with the Federal Reserve's decision window, creating the most intense macroeconomic shock point of the week. The latest results of institutional stablecoin research were released on the same day, with the core dynamics as follows:Metaplanet Inc. (TSE: 3350), as the largest corporate BTC reserve holder in Asia and the third largest publicly traded company holding Bitcoin globally (holding 40,177 BTC at an average price of about $104,000, with a target of 100,000 BTC by the end of 2026), faced a dual-edged sword pressure from the exchange rate yesterday: after the Bank of Japan announced a 25 basis point increase in the policy interest rate to 1.0%, the yen strengthened, superficially lowering the book value of BTC denominated in yen, but Bitcoin subsequently rose against the trend (CoinDesk's headline on the same day: "Bitcoin rallies after Japan rate increase"), with actual improvements in USD-denominated holdings. The company's current holdings are approximately $2.64 billion (estimated at $65,750/BTC), with the latest capital move being the issuance of 8 billion yen (about $55 million) for the 20th bond (EVO FUND) on April 24 for additional BTC purchases. Analysts warn that if the BOJ's interest rate hike triggers large-scale unwinding of "Yen Carry Trade," global risk assets including BTC may suffer systemic deleveraging shocks—however, Metaplanet holds physical BTC rather than leveraged positions, with its main risk being the exchange rate conversion effect rather than forced liquidation.OSL Group (Hong Kong Stock Exchange: 0863.HK) and the School of Business at the Hong Kong Polytechnic University jointly released a white paper on June 16 (The Block included it on the same day at 9:01 am EDT), titled "Cross-Border Trade Payments Will Drive the Adoption of Regulated Corporate Stablecoins." The core conclusion is that the demand for corporate-level cross-border trade payments is the main path to drive the large-scale adoption of regulated stablecoins, with importance surpassing retail consumption scenarios. OSL Group holds the Hong Kong Securities and Futures Commission licenses 7 (automated trading services) and 1 (securities trading), making it one of the few compliant exchanges globally with both institutional custody and practical experience in stablecoin settlement. Previously, it provided institutional clients with approximately $130 million in USDGO stablecoin settlement services in April 2026. This white paper provides an industrial basis for the stablecoin policy framework of Hong Kong's financial regulatory authorities, and, together with Visa's stablecoin settlement of $7 billion annualized scale, SoFi SoFiUSD's launch, and Western Union's USDPT layout, constitutes multiple points of evidence accelerating the global adoption of corporate stablecoins.

RetoSwap disclosed on platform X that the team received a report at 2:02 AM (Beijing time) today that the Haveno trading protocol was under attack. They immediately set the minimum client version to 2.0 through the filter function and suspended trading, as well as banned the attacker's onion address. RetoSwap stated that the team was not attacked, and the vulnerability lies at the Haveno protocol level. The losses seem to be limited to large cryptocurrency asset orders, and fiat currency traders were not affected. The team is evaluating plans to assist affected traders in recovery. Trading will resume after the protocol is fixed.Previously, on May 21, it was reported that RetoSwap lost approximately $2.7 million due to vulnerabilities in the Haveno protocol.

Syscoin released a bridge security incident report, disclosing details of the UTXO-to-NEVM bridging vulnerability incident. It is reported that this incident led to approximately 5 billion SYS being unauthorizedly released on the UTXO side. The related funds have since been returned to the official recovery address and destroyed through the standard OP_RETURN method, making them unusable by the protocol again, and the on-chain reported SYS supply has been restored to the expected value. The bridging function is currently still suspended, and the team is completing the final review and repair.

According to People's Financial News, the AI version of Alipay has officially launched, named "Abao." Alipay has become the world's first super application to achieve full-end AI integration. Currently, the new version has started an invitation-only testing phase and will gradually be opened to all users in the future.

According to Jinshi, the American asset management company PGIM expects the Federal Reserve to raise interest rates three times this year to curb economic overheating, and then reverse the rate hikes in 2027. PGIM pointed out that the U.S. economy is "exceptionally strong," with inflation remaining high, necessitating new strategies. The company also stated that it expects the Federal Reserve to cut rates three times in 2027, with the final rate dropping to 3.375%, below the current level.

10x Research stated that the mechanisms in the options market driving Bitcoin below the $70,000 support level are changing and may even shift to promote an increase. After BTC fell below $70,000, the negative gamma effect in the options market amplified the decline. At that time, market makers who were short gamma were forced to sell during the downturn, causing the market to evolve from a normal pullback to a series of liquidations, with Bitcoin dropping to a low of $65,705. This mechanism has not disappeared but has shifted to a new critical position.At this stage, the largest negative gamma position in the Bitcoin options market is near the current spot price, corresponding to a scale of about $1.8 billion. If price fluctuations occur, the hedging actions of market makers may again amplify the market movements. Driven by factors such as improved market sentiment indicators, potential agreements related to Iran that may reduce inflation risk premiums, and market expectations that the new Federal Reserve chair will adopt a more dovish stance, the options structure that previously led to Bitcoin's decline may be transforming into a force that promotes a rebound.

According to a report by Jiemian News, Ant Group is secretly testing an AI version of Alipay, which disrupts the original user interaction and allows users to access a native AI interface with one click, achieving intelligence in service and fund management.The news states that the launch time for the new version is not yet determined. Ant Group declined to comment.
